2 Samuel 21:20-22

20There was war at Gath again, where there was a man of great stature who had six fingers on each hand and six toes on each foot, twenty-four in number; he also was a descendant of the giants.

21And when he taunted and defied Israel, Jonathan the son of Shimei, David’s brother, killed him.

22These four [warriors] were descended from the giant in Gath, and they fell by the hands of David and his servants.
